When you are going to look at used SUV, I think what matters the most is the overall condition and the price you are getting it for.
I sold my 1989 HJ60, in December last year and after searching for almots an year , as my plan used to get changed (LC80/Prado/Surf), I finally got an immaculate 99 Surf al hmad o lillah with 1KZTE, and I am quiet happy with its mileage too, I am getting 8km/l in city and 11km/l on motorway @110km/h.
Although it has cost me alot more but when I looked at its condition, I simply coudnt resist it, so I have to take the bullet.
In the price I got it for I could have bought a 96 Prado but overall the condition overrules the preset priorities or atleast in my case.
Checked it thoroughly at Toyota Ravi Motors on Saturday and all she needs is to change all the oils, filters, belts and Timing belt.
